Description
The Omega DV40 ER Collet Chuck – Mini Type ER11 is a compact, high-speed toolholding solution designed for DV40 spindle systems. It leverages the robust ER collet system to deliver strong gripping force and excellent concentricity, keeping tools securely centered during milling and drilling up to 25,000 RPM. Fully compatible with DIN69871 DV40 spindles, it features a 70mm gauge length (Form AD) and offers two precision balance options—G2.5 and G6.3—so you can match accuracy to your application needs.
Designed for tight workspaces, this mini ER11 chuck provides reliable performance where space is limited. The compact form and tight gripping range minimize tool runout and vibration, helping you achieve consistent diameters and smoother finishes even at higher speeds. The selectable balance grades let you tailor performance to the task at hand, supporting longer tool life and reduced downtime in demanding production environments.
